Most laptops are smart enough to see the external monitor and let you start using it, keeping the laptop’s power on while the lid is closed.. Whether you’re printing on the road or at ho
Trang 1Some cards may require extra software to make them go It will state so
in the card’s manual Other cards, like many USB devices, can just be
plugged in, and they’re off and running
The most common type of PC Card available today is a wireless
network-ing card Installnetwork-ing the card is only half the battle The rest is properly
configuring your laptop to connect to a wireless network Refer to
Chapter 9 for the gory details
The device installed in Figure 7-5 is an IEEE 1394 (or FireWire) port
expansion card
Using the PC Card
After the PC Card is inserted and properly set up, you can use its features
In fact, you can keep the card inside your PC for as long as you need those
features
Note that some cards hang out of the PC Card slot a bit Some may have
pop-out connectors Be careful of those! They can get caught on things, so you
might consider removing such the PC Card before you pack up and tote the
laptop away
If you’re adding USB or IEEE 1394 expansion with a PC Card, then you
can start using those ports right away Refer to the sections on using
USB devices earlier in this chapter for more information
Adding a network device allows you to use that device — providing
that networking options have been properly configured (as covered in
Chapter 9) But after you’ve set up networking, you can remove and
rein-sert the networking PC Card as often as you like
Removable storage devices can be used after they’ve been inserted and
recognized by Windows But be sure to properly remove the device, as
covered in the following section
Removing the PC Card
Though all PC Cards can easily be pinched and yanked out of their cozy
sock-ets, that’s not the best way to treat your PC’s hardware Instead, follow these
steps:
1 Click the Safely Remove Hardware icon in the System Tray.
Refer to the section, “Removing external storage,” earlier in this chapter
for the details
125
Chapter 7: Expanding Your Laptop’s Universe
Trang 2A message appears telling you that the device can be safely removed.
3 Pull the PC Card out from its slot.
Some cards need a bit of help here You’ll have to find a small button tothe right of the card Pushing the button in a ways makes it pop outabout a half inch or so Then press the button back into the laptop tohelp push out the PC Card
Store the PC Card in a proper place, such as in your laptop bag or in a drawer
or cubby with the rest of your laptop gear The idea here is to keep the PCCard from being stepped on or crushed by a Big Gulp cup
Adding Some Big Boy Toys
If you plan to land your laptop in one place all the time, then you’ll probablywant to upgrade its teensy portable features with some more robust desktopcounterparts Specifically, I speak of the keyboard, monitor, and mouse Any
of these desktop-sized items can be added to and used with a laptop instead
of their feeble laptop counterparts Use one Use them all It’s up to you
Yeah, if you’re really picky, you can even take a spare keyboard andmouse with you when you travel
Note that keyboards and mice do not need separate power supplies towork, but monitors do!
If you really want a larger monitor with your laptop, and you want totake it with you, then consider upgrading to one of the many large-format or widescreen laptops with those sexy, humongous screens
They might not be as portable as smaller laptops, but yowza!
Using an external keyboard
If you miss the full size and action of a real PC keyboard, then get one! Justplug it into your laptop, either into the keyboard port or a USB port,whichever is available You can start using the keyboard the second that it’splugged in
Note that adding an external keyboard often does not disable the laptop’sinternal keyboard You can use both! But you’re probably not crazy enough
to do that
Trang 3When you’re done using the full-sized keyboard, simply unplug it.
If all you’re yearning for is to have a separate numeric keypad, then
con-sidering getting only that You can pick up a USB numeric keypad, which
is just the keypad and not the entire keyboard, at most computer stores
and office supply stores
Sometimes, the only way you can add a non-USB keyboard to your
laptop is by getting a port replicator or docking station
The standard color for a PC’s keyboard connector — the hole somewhere
on your laptop for plugging in the keyboard — is purple
Connecting a second monitor
or video projector
Most modern laptops are automatically equipped to handle two monitors,
the laptop’s own LCD and an external monitor This is because many laptops
are often used for storing and showing presentations, and it just makes sense
to have the laptop all ready to go in that respect
To add the external monitor, locate the monitor connector on your PC’s
rump Plug in the monitor, and you’re ready to go You can use that monitor
in conjunction with your laptop’s LCD or as your laptop’s only display
On some laptops, the same image appears on both the LCD and the
external monitor
If you want to use the external monitor exclusively, then just close your
laptop’s lid Most laptops are smart enough to see the external monitor
and let you start using it, keeping the laptop’s power on while the lid is
closed When you open the laptop’s lid, control returns back to the
laptop’s LCD
Note that if you close the lid, it helps to have an external mouse or
keyboard connected to the laptop so that you can still use your
software
The monitor connector can also be an S-video connector This allows
you to connect your laptop not only to an external monitor, but also to
many TV sets, VCRs, and DVD players Refer to Chapter 5, Table 5-1 for
more information
127
Chapter 7: Expanding Your Laptop’s Universe
Trang 4Using two monitors at once
If you want to use two monitors at once, you need to direct Windows to do
so After connecting the second monitor, follow these steps:
1 Open the Display Properties dialog box.
Refer to Chapter 6 for more details
2 Click the Settings tab.
You see both monitors displayed in the top of the dialog box
3 Click the second monitor.
4 Choose the Extend My Windows Desktop onto This Monitor option.
5 Click the Apply button.
6 Adjust the monitors’ positions in the area near the top of the dialog box.
You can drag the number 1 or number 2 monitor around to help alignthe two desktops Use the mouse to grab and drag each monitor into aproper position relative to each other
7 Click the OK button when you’re done.
Note that the laptop’s LCD is always the first display It will be the only displaythat contains the taskbar and Start button And though you can drag windowsand icons to the second display, they’ll all hop back to the first display thenext time you restart Windows
Gotta getta mouse
A computer mouse is perhaps the best companion you can buy for your laptop.Not that flat, odd, mouse pad thing! I’m talking about a real computer mouse.Just grab your favorite desktop mouse and plug it into your laptop It makesfor a much more enjoyable laptop experience — even if you often have to useyour thigh to roll the mouse around
Mice makers are aware of laptop owners’ fondness for “real” computer mice
So they have a whole line of options available to you You don’t have to get
a full-sized desktop computer mouse No, you can opt for one of those newmini-mice for laptops They work just like desktop mice, but they’re abouthalf the size Some are even wireless And they’re all better than using thatsilly touch pad
Trang 5Adding an external mouse may or may not disable your laptop’s touch pad If
you do want the touch pad disabled, then use the Mouse icon in the Control
Panel to disable it (providing that it’s a hardware option for your laptop)
Printing
When Adam Osborne originally proposed the portable computer, portable
printing was not part of the big picture Instead, printing is something that
can be done later You can transfer your on-the-road files to your desktop
system, or wait until your laptop is docked, before printing But portable
printing?
True, there are portable printers I’ve used the Cannon Bubble Jet portable
printer with my laptop It’s not that heavy, has full color, is fairly fast, and it
runs off flashlight batteries So there are on-the-road printing options if you
want them
Whether you’re printing on the road or at home, the following sections
describe how to set up and use a printer — or even a printer alternative —
with your laptop computer
Setting up the printer
Though the laptop comes with a connector mysteriously called the printer port,
you probably want to use a USB printer with your laptop Only if you already
have a printer and it’s a traditional (non-USB) model should you consider
connecting it USB is the wave of the future, man!
To connect the printer, follow these steps:
1 Plug in the printer, but ensure that it’s turned off.
Also, set up the printer with ink and paper and all that other good stuffaccording to the directions that came with the printer
2 Connect a USB cable to the printer and to your laptop.
Or if you just cannot stand my advice, plug a standard printer cable intothe printer’s rump or into your laptop’s very expensive port replicator
or docking station
129
Chapter 7: Expanding Your Laptop’s Universe
Trang 6Windows should instantly recognize the printer, as shown in Figure 7-6.Then, because you’re using a USB printer, it will know the printer’s nameand brand and it will even completely install software for you, settingeverything up just so.
When you’re using the older printer-port type of printer, you’ll probablyhave to use some kind of software installation disk that will just driveyou nuts Good luck!
After the printer has been set up and recognized by Windows, you can eitherprint or you can save some energy and turn the printer off You can even dis-connect it when you don’t need it Reconnecting the printer simply reactivatesits support in Windows
The printer port might not be available on your laptop You may need
a port replicator or docking station to access the old-fashioned, sillyprinter port
Leave your printer turned off when you’re not using it
You can unplug the printer’s USB cable without having to use the SafelyRemove Hardware icon in the System Tray Just unplug the cable andWindows bids adieu to your printer
Yes, it’s not a good idea to unplug or turn off your printer while it’s printing
If you’re having trouble adding your printer, open the Control Panel anddouble-click the Printers and Faxes icon to display the Printers andFaxes window Click the Add Printer task in that window to run the AddPrinter Wizard, which should help you complete the printer setup task
Printers work by using a driver, which is a software program that controls
the printer Windows knows about many printers and comes with theirdriver software For other printers, you need to find a CD with the driversoftware that came with the printer, or you have to visit the printer man-ufacturer’s Web site to download the latest driver
Wow
Trang 7Printing in Windows
To print a document, e-mail, or anything in Windows, you use the File➪Print
command This displays the Print dialog box, which can also be summoned
by using the Ctrl+P keyboard shortcut A sample of this dialog box is shown
in Figure 7-7
Here are the quick steps you can take to work through this dialog box:
1 Choose your printer from the list of printers.
This is also where you select the Microsoft Fax, or your computer’s fax
software, to send a fax
Note that some printers visible in the window are network printers,
available only when your computer is plugged into the network Printing
to them is fine; the document waits until you reconnect to the network
before it prints
2 Select the range of pages to print.
3 Select the number of copies.
4 Click the Properties or Preferences button to set individual printer
settings.
For example, if you want to print in black ink only on a color printer, you
would set that option by clicking the Properties or Preferences button,
and then setting the printer’s color in the dialog box that appears
5 Click the Print button to print your document.
Trang 8Also refer to Chapter 6 for information on setting a default printer, as well aswhere to find the Printers and Faxes window.
Options for when you don’t have a printerOnly the truly clever can print when a printer is not available And for therest of us, I offer these suggestions:
Most hotels have business centers where you can temporarily connect
to a printer and get your stuff on paper
Some office supply stores offer printing services Print shops and placessuch as Kinko’s also have printers available for rent by the hour or bythe sheet
Fax machines are printers If you know of a fax machine nearby, just sendyour document as a fax Note that plain paper faxes are preferred for this;avoid wax-paper faxes if possible And note that faxes do not print in color
As a last, desperate move, you might just try printing to the printer you use athome or the office, even though it’s not connected While this won’t get you acopy right away, the item to be printed sits and waits on your computer until
you’re once again connected to the printer At that time, it will spool out of
storage and print as you intended
What about printing to disk?
Once upon a time, you could save printer
infor-mation to disk like a file Then you printed that
file by sending it directly to the printer, either via
a DOS command or by dragging that file onto
your printer’s icon This worked well in earlier
versions of Windows but does not work at all in
Windows XP — despite the Print to Disk option
still being available in the Print dialog box
A great alternative for the old Print to Diskoption is to create an Adobe Acrobat, or PDF,document instead For this, you need to buy theAdobe Acrobat Writer software or an equiva-lent The Acrobat Writer software appears inyour laptop’s list of printers Select it for print-ing, and the result is a PDF document that’sreadable on just about any computer

Power Management Madness
In This Chapter
Knowing various types of batteries
Locating your laptop’s battery
Monitoring battery usage
Charging the battery
Using a spare battery
Conditioning the battery
Disposing of dead laptop batteries
Managing power usage in Windows XP
The first efforts made by the engineering team to make things portable
were done primarily to satisfy management and its quest for return solutions Stuffing a desktop computer’s components into a single caseand bolting a handle on top definitely makes that computer portable and satis-fies management’s desire for cheap solutions Yet at some point, the engineershad to wonder whether they could do better
low-cost/high-Indeed, to make something truly portable, it must also be free of the powercord The inspiration here just had to be the portable radio It came with ahandle but no power cord Instead, the power was supplied via common
flashlight batteries Batteries Yes! That must be the solution For a computer
to be truly portable, it must get its power from batteries instead of a wallsocket (And it still must have a handsome leatherette carrying handle.)This chapter is specifically about the battery inside your laptop computer
The general topic, of course, is power management That’s the goal of using
any battery; use it as you need it, but always with a mind to stretch thatpower as far as you can
Trang 10The Battery Will Get a
Charge Out of This!
The thing that makes your laptop go on the road, or I should say the thing
that powers your laptop on the road, is a battery If your laptop “goes” on the
road, be sure to clean up after it
Having a battery in your laptop is not news Even so, you may have some tions about the battery, and you probably want to know how best to use it and
ques-get better performance from it Yes, indeed, you probably have a battery of
questions! Ha! So before this paragraph degenerates further, the following sections touch upon battery issues, important and trivial
Types of batteries
A battery by any other name would still sting like heck when your big brotherfooled you into putting it into your mouth
Just as a good gardener knows that there is more than one type of rose, so
is there more than one type of battery They all provide electricity But yetbetween each battery type, there are plusses and minuses
Alkaline This is the most common type of battery, normally used in
flash-lights, portable radios, remote controls, smoke alarms, and kids’ toys Theadvantage here is that you can find these standard-sized batteries anywhere
A few portable computing devices (printers, handhelds) use them But fewlaptops do The reason is that they’re not rechargeable You use them, youthrow them out (properly, according to the environmentally safe battery dis-posal rules of your jurisdiction)
Lead acid The most common place to find the scary-sounding lead-acid
bat-tery is in your automobile These batteries are durable, long-lasting,
recharge-able, but they’re also heavy and, well, they’re full of lead-acid! Yikes!
More commonly, in a laptop computer, you’ll find one of the following types
of batteries:
Lithium-Ion This is the type of battery you want to have in your laptop It’s
lightweight and better performing than the other types of batteries UnlikeNiCads or NiMH batteries, Lithium-Ion batteries don’t have The DreadedMemory Effect There is usually a rapid charging option with Lithium-Ion batteries, which is good when you’re in a crunch Finally, this type of battery
is more environmentally friendly than the other types And it has a sounding name
Trang 11cool-Nickel Cadmium (NiCad) Of all the rechargeable types of consumer
electron-ics batteries, the NiCad is the oldest It’s frowned upon now, mostly because
this type of battery suffered terribly from The Dreaded Memory Effect Even
so, NiCads offer great performance and until the better battery technologies
came along, they dominated the portable power storage market
Nickel-Metal Hydride (NiMH) This type of battery was one of the first
suc-cessful alternatives to NiCads A NiMH battery is longer lasting than a NiCad,
but sadly it suffers from The Dreaded Memory Effect just as badly as the
NiCad
Of all these batteries, odds are very good that your laptop has a
Lithium-Ion type That’s pretty much state of the art
Lithium-Ion is often abbreviated as LION Because that’s also the word
for a big, ferocious kitty cat, I use “Lithium-Ion” in this book
You can confirm which type of battery your laptop has by looking at its
label Refer to the next section
If you haven’t yet purchased a laptop, ensure that you get one that has a
Lithium-Ion battery
A few laptops out there are still using NiMH batteries This is fine, of
course But you might want to check to see if there is a battery upgrade
option to the Lithium-Ion type
Your laptop might actually have a secondary, alkaline battery inside It’s
used to power the laptop’s internal clock, which keeps track of the time
even when the laptop is unplugged or the battery has drained

Chapter 8: Power Management Madness
Fuel cells
Laptops of the future, as well as other portable
devices, won’t be using batteries any more
Instead, they’ll be equipped with something
called a fuel cell.
Fuel cells use a magical combination of
chem-istry and physics to provide power for a much
longer period of time than a typical battery When
the fuel cell gets low, you simply add more fuel
to it — similar to filling a gas tank Then the fuel
cell is ready to go, powering your portable
elec-tronics until it needs refilling again
Certain types of fuel cells are available today, butthey’re still too large and bulky to be used with
a laptop computer The present time schedulestates that by the year 2010, fuel cells will besmall, light, and compact enough for use in laptopcomputers When that time comes, power man-agement on your laptop will become a differentcreature, and battery-saving tips and techniqueswill become a thing of the past
Trang 12things powered for the minute or so that it takes you to swap a spentmain battery out with a fresh one See the section, “The spare battery,”later in this chapter.
Refer to the sidebar, “The Dreaded Memory Effect,” for information on,well, The Dreaded Memory Effect
Using unapproved batteries in your laptop may lead to bad things, such
as, oh, the laptop exploding
Another thing to look for is a smart battery This type of battery contains
circuitry that communicates with the laptop, letting it know the battery’scondition so that you get better power control Such batteries last longerdue to better power management
Finding your laptop’s batteryTake a moment to locate your laptop’s battery Odds are good that it loads
in on the bottom of the laptop, though many laptops have their batteriesinserted through a hole or door in the side
The battery may be labeled, describing what type of battery it is (see the vious section), as well as other information about the charge it holds, serialnumber, replacement information, and so on Note that often this informationmay be printed on the laptop case instead of or in addition to being on thebattery
pre- Be aware of where your battery is stored in your laptop You may need
to remove or replace it in the future
Most laptops use a few sliding locks or clips to help keep the battery inplace Do not force a battery into or out of your laptop
Batteries get warm as they’re being used That’s simply their nature.However:
Watch out if the battery gets too hot! For example, the battery is too hot to touch or hold for more than a few seconds That could be a sign
of a malfunctioning battery, and such a thing is dangerous Phone your
dealer or laptop manufacturer immediately if you suspect that the tery is running hot
bat-Monitoring the batteryThe laptop’s battery drains as you use it, which is to be expected In modernlaptops, you should plan for at least two or three hours of active computer
Trang 13use under battery power The rate of drain does vary, however, depending
on what you’re doing with the laptop And, naturally, depending on what
you’re doing, that time may pass by rather quickly
In Windows XP, you can monitor the battery by viewing the tiny battery icon
in the Notification Area (or System Tray) The icon graphically shows how
much power is left; the icon’s color “drains” out as you use the laptop But
often that display is too tiny, so what you can do is point the mouse at the
icon to see a pop-up bubble explain how much juice you have left, as shown
in Figure 8-1
In Figure 8-1, Windows shows that one hour, three minutes are left for battery
life, and the battery has about 31 percent of its power remaining
You can also monitor the battery usage from the Control Panel’s Power
Options icon The Power Meter tab offers up lots of juicy information on
the battery’s status, as shown in Figure 8-2
Trang 14Your laptop manufacturer may have also included other battery tools, such
as a battery monitor window, a special keyboard shortcut to display batterystatus, specific battery icons in the Control Panel, and so on Be sure toreview what you have, as often these tools can be better or more useful thanwhat Windows XP offers
The battery icon may not appear in the Notification Area when yourlaptop is being AC powered
To ensure that the icon shows up, even when the laptop is plugged in,open the Control Panel’s Power Options icon, click on the Advanced tab,and put a check mark by the Always Show Icon on the Taskbar option.Click OK
On some laptops, a different icon may appear in the Notification Areawhen the laptop is AC powered
The battery icon on your laptop’s row-o-lights may also indicate howmuch charge is left by changing color or even the amount of light show-ing through Refer to Chapter 5 for more information on finding the bat-tery light or icon on your laptop
AC powered means being powered by electricity from a wall socket.
DC powered means being powered by the battery.
The Dreaded Memory Effect
In the old days of the NiCad and even NiMH
bat-teries, the mantra went that you had to fully
dis-charge the battery, all the way down to zero,
before you even considered recharging the
thing This was true and necessary: If you didn’t
fully drain the battery, then it began to lose its
potency over time
What happened, especially with NiCad batteries,
was that the battery would “remember” how long
it was used So if the battery held one hour of
power when fully charged, but you recharged it
after only 30 minutes of use, then the former
one-hour battery would become a 30-minute battery
That’s The Dreaded Memory Effect
To avoid The Dreaded Memory Effect and to
pro-long the life of their batteries, NiCad users would
insist on fully draining the batteries each and
every time they were used Laptop owners wouldhave to wait until their machines completely shutdown before recharging (Remember, NiCads arenot “smart” batteries either.) Even so, some userswould give up, and eventually their rechargeableNiCads would be down to only ten minutes ofpower — not enough
Today’s Lithium-Ion batteries do not have TheDreaded Memory Effect at all You can use themfor a minute, then recharge, and the battery willstill be as good as it was when you bought it Soboldly use your battery without fear And nexttime someone mentions The Dreaded MemoryEffect, giggle with a smug laugh of confidence,secure in the knowledge that you’re safe fromthe power problems of the past
Trang 15Smart battery technology is responsible for the ability of Windows to
determine how much power is left in the battery But still be aware that
such a thing is an estimate Different things can affect battery life So
don’t bet real money on how much longer your laptop can survive off
the battery
Refer to Chapter 6 for more information about the Control Panel in
Windows
What happens when the power gets low
You know that terrible feeling you get immediately after a power outage?
You know, everything in the room goes dark or turns off It’s startling! Well,
the idea behind using your laptop is to avoid that feeling when the battery’s
power starts to go
Thanks to smart battery technology, your laptop computer gives you a good
deal of warning before the battery poops out It’s enough time to finish what
you’re working on, save, close programs, and shut down the computer
properly
Figure 8-3 shows the low battery bubble warning that Windows pops up
That’s the initial warning A second warning appears just before the battery
dies It should say, “I told you so,” but actually, it just warns that a power-off
situation is imminent At that point, the laptop ignores you and either shuts
down or goes into hibernation
What the laptop does when the battery dies, or when the two warnings (
initial and imminent) appear, is set in the Power Options dialog box, Alarms
tab, shown in Figure 8-4
The first warning is known as the Low Battery Alarm You activate it by
putting a check mark by the Activate Low Battery Alarm When Power Level
Reaches option, as shown in Figure 8-4 Use the mouse to adjust the slider,
setting the percentage of battery life left when the Low Battery Alarm kicks
in You can further use the Alarm Action button to tell Windows what to do:
to pop-up a warning, beep, or shutdown (More on that in a moment.)
Trang 16The second warning (refer to Figure 8-4) is the Critical Battery Alarm I highlyrecommend activating this option and setting the slider to something low,such as the 3 percent shown in Figure 8-4 Click the Alarm Action button tosee which options to take when the power does get low.
In Figure 8-5, you see the options available for when the power gets criticallylow These things take place automatically, controlled by Windows The com-puter can sound an alarm or display a message But more importantly, youcan direct the computer to hibernate, stand by, or shut down completely, asshown in the Alarm Action area of the dialog box
Trang 17Also notice the Run a Program area If necessary, you can configure a certain
program to run when the power gets low, such as a utility to immediately back
up your work files to a flash memory card, send remaining e-mail, or a number
of other options
After the critical warning appears, the laptop does as its directed, shutting
down or suspending or hibernating It remains in this state until you either
replace or recharge the battery, or you plug the laptop back into the wall for
power
That critical battery notice is serious Computer time is over! If you
ignore the warning, your laptop will stop working And so will you
When the low battery notice sounds or appears, and you are blessed
with a second battery for your laptop, pop it in and keep working! Refer
to the section, “The spare battery,” later in this chapter
The best thing to do when power gets low: Plug in! This is why I always
take my power cable with my laptop wherever I go
Charging the battery
This is easy to do: Charging a laptop battery is done by simply plugging the
laptop into a wall socket Immediately, the laptop switches from battery (DC)
power to AC power, and the power management hardware inside the laptop
begins to recharge the battery
You can recharge your laptop’s battery whether the battery is fully drained
or not Especially if your laptop is using a Lithium-Ion battery, this makes
no difference Refer to the sidebar, “The Dreaded Memory Effect,” for more
information
Note that Lithium-Ion batteries do have a rapid-charging option This option
is either available in a custom tab inside the Power Options dialog box, or
it may be available through special battery software that came with your
laptop In a pinch, a rapid charge can save time But normally, you want a
nice, full, slow charge for your laptop’s battery
I generally leave my laptop plugged into the wall whenever I can
There is no need to fully drain your laptop’s Lithium-Ion battery every
time you use it
It does benefit NiCad and NiMH batteries to be fully drained before
they’re recharged That type of battery lasts longer and retains most of
its potency if you fully drain it

Chapter 8: Power Management Madness
Trang 18charging unit You can use that to charge extra laptop batteries, shouldyou have them.
The battery continues to charge, even when the laptop is turned off
It’s been said that if you’re using a laptop while you’re charging the tery, it will take longer to recharge the batteries than when the laptop
bat-is turned off Thbat-is might have been true once, but it bat-is no longer truetoday; feel free to use your laptop while the battery is charging
Never short a battery to fully drain it By short, I mean connecting the
two terminals (positive and negative) directly so that the battery simplydrains This is very bad and can cause a fire Don’t do it
The spare batteryOne option you probably ignored when you bought your laptop was getting
a second or spare battery This is must for people who are seriously on theroad or in a remote location where a long time is spent away from the powersocket
Before you use a spare battery, ensure that it’s fully charged Either charge it inthe laptop, or use an external charger (if available) Put the fully charged, sparebattery in your laptop case or in any non-conducting (metallic) container Thenhead out on the road
If your laptop has some type of quick-swapping ability, then when the powergets low, you can just eject your laptop’s original, spent battery and quicklyinsert the spare battery But be sure that your laptop can survive such aheart transplant before you attempt it!
If your laptop doesn’t have the ability to hot-swap batteries, then just turn off(or hibernate) the laptop when the original battery is nearly spent Removethe old battery, insert the fresh one, and then turn the laptop on again
Yeah, it’s a good idea to get a laptop that supports hot-swapping ies in the first place, if this is a trick you plan on pulling often
batter- I recommend labeling the batteries with a Sharpie so that you don’t getthe two (or more) confused and accidentally insert a dead battery
You can buy a spare battery from your dealer, or also from stores that sell extra batteries, such as iGo (www.1800batteries.com) orBatteries.com (www.batteries.com)
Be wary of generic batteries! Always try to get manufacturer or turer-approved batteries for your laptop Anything less and you can runthe risk of setting your laptop ablaze! It’s happened!
